When your furnace is running correctly, it should give heat without generating too much disruption. While it’s expected to hear your furnace making noise as it turns on, other sounds are signaling your furnace requires immediate professional support.
Here are some of the most frequent furnace noises and what they might mean. If your furnace is making an odd noise, our friendly heating pros are here to fix the problem with the best furnace repair in Albuquerque, New Mexico.
1. Furnace Making a Banging Noise
You may have a critical situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it might indicate there could be a couple of problems. These involve gas building up in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system gets grimy over the years, so that’s why it’s important to set seasonal furnace maintenance with I-Deal HVAC. One of the things our techs do during this service is clean your furnace’s burners. When this component gets grubby, you could hear your furnace making a loud rumbling noise if ignition takes longer than normal. The following gas buildup might crack your furnace’s heat exchanger, where natural gas turns into warm air. Any breaks in it can leak carbon monoxide, which is normally vented outside. This hazardous gas can be fatal in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, I-Deal HVAC recommends turning it off and reaching us at 505-445-1250. Significant natural gas in your furnace or a fractured heat exchanger are dangerous issues that necessitate prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to provide warm air around your home. If the ductwork wasn’t installed right or is getting dated, it can be noisy when your furnace is heating. This may be the case if your furnace makes a banging noise when it shuts off. Call I-Deal HVAC at 505-445-1250 and we’ll figure out the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound often means there’s an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to work on the correct voltage. If wires or the box needs to be tightened, you could notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves hot or cold air around your space, and a capacitor, which turns on the motor. If either of these components are fading, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it could be due to something little, like a loose screw, or something major, like a broken part. In either case, we urge you to shut your furnace off and contacting our heating professionals at 505-445-1250 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s attempting to tell you it could use some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn down or a bearing could need to be lubed. We know that maintenance often slips your mind, but our techs can get your furnace running quietly again fast.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You might also notice whistling while the furnace is running if a floor vent isn’t secure. If you’ve checked your vents but are still noticing whistling, I-Deal HVAC can help. It’s critical to get loose ductwork repaired fast, as it can make comfort problems in your home and drive up your gas costs.
6. Furnace Making a Grinding Noise
It’s not a positive sign if you detect your furnace making a grinding noise. This metal-on-metal racket typically means there’s trouble with your furnace’s blower. Switch off your furnace off right away and call us at 505-445-1250 for help.
